Question

Select the correct answer from each drop-down menu.

Offspring inherit genes from their parents, and these genes determine their physical characteristics.

According to the law of (blank), a heterozygous organism has about a (blank) chance of producing gametes with the recessive allele.

a:
1. segregation
2. genetics
3. assortment

b:
1. 25%
2. 50%
3. 75%

Answer 1

In Mendelian genetics, according to the law of segregation, a heterozygous organism has a 50% chance of producing gametes with the recessive allele.

Step-by-step explanation:

The question relates to Mendelian genetics and the inheritance patterns of alleles. According to the law of segregation, a heterozygous organism (one that has two different alleles for a trait) has a chance of producing gametes with the recessive allele. During gamete formation, alleles for a trait segregate so that each gamete carries only one allele for each gene. This results in a 50% chance of transmitting either allele to the offspring. If an organism is heterozygous for a given trait (Aa), then it has two different alleles: one dominant (A) and one recessive (a). Thus, there is a 50% chance that a gamete produced by a heterozygous organism will contain the recessive allele (a).

Therefore, the correct answers to fill in the blanks would be:
