Adaptive
Inherited <<<<
Biological
2. _____ is conisdered to be the Father of Modern Genetics because of his work with pea plants and their offspring. *
Gregor Mendel <<<
Albert Einstein
Reginald Punnett
3. When a true-breeding pea plant with yellow seeds is crossed with a true-breeding pea plant with green seed, what color(s) will the offspring's seeds be? *
All will be yellow.
All will be green.
Half will be yellow, half will be green. <<<
4. ____ are large bundles of tightly coiled DNA. *
Alleles
RNA
Chromosomes <<<<
5. Human sex cells have exactly ___ chromosomes. *
23
46 <<<<
92
6. If both pairs of alleles in a pair of genes are the same, then the organism is said to be ____ for that trait. *
homologous <<<
homozygous
heterozygous
7. Which trait is dominant, tallness or shortness? *
Tallness <<<
Shortness
Neither, offspring would be "medium-sized"
8. The following list contains possible combinations for pea plant seed shape. Round (R) is a dominant trait, and wrinkled (r) is a recessive trait. Choose the combination(s) that would result in a plant with wrinkled seeds. *
Rr
RR
rr <<<<
9. Which controls the characteristics of an organism? *
proteins
alleles
DNA <<<<
10. Which statement best describes the difference between a gene and an allele? *
An allele is a section of a chromosome that typically contains the code for a particular protein. A gene is one of two or more alternative forms of an allele.
A gene is a section of a chromosome that typically contains the code for a particular protein. An allele is one of two or more alternative forms of a gene.
An allele is a section of DNA , which typically contains the code for a specific protein that determines a specific trait. A gene is a section of an allele.


I DONT KNOW 10, PLEASE HELP ASAP!!!

Sagot :

xokkxo
literally just had a test on this today :)
1 is correct.
2 is correct.
3: does true breeding like a purebred/homozygous/two of the same traits?
if so, all of the plants will show the dominant allele, so the answer is B
4 is correct.
5: 23 because when they combine, the chromosomes mix, and there are 46 in a regular cell. Half com from one parent, and half from the other, so the answer is A
6: homo is a prefix that means “same”, and zygous has something to do with genes, so the answer is homozygous
7 is correct
8 is correct
9: i have a strange felling that it is alleles, but DNA could also work, so I’m not quite sure on this one, sorry…
10: alleles are the different forms of a gene. Genes are transferred to you from your parents hereditarily. An allele for stem height would be T or t, but a gene would be TT, Tt, or tt.
I really hope this helps you! It was a hard unit for me, but i did get 100% on the test, and I’m sure you can too.

Answer:

A gene is a section of a chromosome that typically contains the code for a particular protein. An allele is one of two or more alternative forms of a gene.

Explanation:

I agree with the other answer but I think this is #10.
